So you have a few licenses and can’t remember which one is on which computer? To check out which license key is on your computer do as follows:
1. Click START and type “regedit” and hit enter.
2. In the resulting window please go to HKEY_CURRENT_USER > Software > inFlow Inventory.
3. In the right-hand window pane you’re looking for the “LicenseKey” and that will tell you the license key you’re using on this computer.
Repeat the process on each computer whose license key you need to check.
